Pankaj Jay Pasricha has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: In the case where the living tissues in the patient's body is resected as well, it is possible to suture the resected portion immediately without replacement with another treatment device after resection. Thus, prevention of bleeding from the resected portion or earlier repair of an ulcer that occurs with the resected portion can be carried out for the patent lowly invasively and easily.

Abstract: A tissue puncturing system used to suture tissues in a body cavity including: an endoscope; a flexible sheath having a distal portion provided with at least a side opening and a lumen, through which an endoscope may pass; at least one mechanism for puncturing tissue disposed in the flexible sheath, and having a pointed end, which is movable from a first position to a second position; and an operation mechanism for moving the mechanism for puncturing between the first and second positions.
Abstract: A cryoprobe instrument for endoscopic use has been provided that permits the delivery of liquid or gaseous cryogens in the form of a spray. In an embodiment, the cryoprobe instrument includes an elongated, flexible tube having a fluid passage defined therethrough; a proximal connector portion provided at the proximal end of the tube for coupling the tube to a pressurized source of cryogenic refrigerant; and a nozzle tip mounted to the distal end of the tube. The nozzle tip has an outlet orifice constructed and arranged such that through the Joule-Thompson effect, cryogenic refrigerant exiting through the outlet orifice rapidly and substantially expands and cools.

Abstract: A method, composition and kit for effecting hemostasis of a bleeding point and/or dissociating an adherent blood clot at a lesion site on an internal organ, include a composition comprising hydrogen peroxide and surfactant. The composition is applied to the site thereby effecting hemostasis and clot dissociation and clearing the field for endoscopy.
Abstract: A stent, for example for maintaining the patency of a duct such as a biliary duct, is provided that includes a plurality of radially extending wings. The wings project from a core which has a guide wire or wire stylet lumen. Each of the wings preferably includes a plurality of minute, longitudinally extending grooves for bile flow even in the event of tumor ingrowth. Advantageously the core itself is preformed into a helical configuration.
